The original Zero Tolerance 0454 was an award-winning collaboration between ZT and custom knife designer Dmitry Sinkevich. But it was also a very Limited Edition knife.

So ZT is doing something about that with the new 0450. While based on the original’s streamlined form and high-performance function, this new and more compact version will be much more readily available. With its 3.25-inch blade and lightweight-yet-stronger-than-steel titanium handles, the 0450 has a sleek and sophisticated look that, we think, makes it a perfect EDC.

ZT built it with an S35VN stainless blade that sharpens to a razor edge, holds it well, and can be resharpened easily. The knife opens smoothly and easily with the KVT ball-bearing opening system and built-in flipper. A titanium frame lock with hardened steel lockbar insert ensures solid lock up. Polished pivot hardware just adds to the 0450's refined good looks.

Frame Lock
Developed by Chris Reeve, it functions like a liner lock but the lock is comprised of one of the handle scales. It's an extremely strong and easy to manipulate lock.

Pocket Clip
Includes a pocket clip for easy accessibility and a more secure carry.

Titanium Handles
A nonferrous metal, it's prized for its high strength to weight ratio and is often used on higher end knives.

Very light and compact for a blade that can puncture soft body armor. Only Con is the smooth surface on the thumb side of the Ti liner/handle...if they added serrations in the area by the logo where your thumb needs to get purchase in order to repeatedly and reliably open the blade, the slick Titanium surface makes it tough.

Super fast shipping from knife center (thank you). Perfect lock up, only ZT that I have that can pass mild spine wack, why not others. Flipping action perfect. Centering great. Wish this was my first ZT knife it would be all i need. Not a fighting knife but I would not use a knife to fight with anyway. Rides in pocket comfortable and lite weight. Pocket clip could be deep carry but no biggy as it works.
